Abstract

Systems and methods for sonification, user influence through sound, and biofeedback, sonification of motion and physiological parameters during physical exercise and the use of music and sound in order to influence the emotional, psychological and physiological state of an exerciser, and the use of sonification and influence in a feedback loop to create a particular exercise experience for a user. A digital music player comprises physiological sensors, a controller, a user interface, a music decoder, a music playback modulator, and an audio data store. The user interface allows a user to specify target values for the physiological sensors as a function of time, the controller selects a playlist of audio data based on the target values, the music decoder decodes the audio data in a sequence corresponding to the playlist, and the music playback modulator causes the sequence and/or the decoding to be modified according to the values of the physiological sensor.

1 . A digital music player comprising: a physiological sensor; a controller; a user interface; a music decoder; a music playback modulator; and an audio data store; and wherein said user interface allows a user to specify target values for said physiological sensor as a function of time for at least one value of time; wherein said controller selects a playlist of audio data stored in said audio data store based at least in part on said target values; wherein said music decoder decodes said audio data in a sequence wherein said sequence corresponds to said playlist; and wherein said music playback modulator causes said sequence or said decoding to be modified according to the values of said physiological sensor.  
   
   
       2 . The digital music player of  claim 1 , wherein said modification of said sequence of said decoding comprises the evaluation of diffusion coordinates of said audio data.
